About
Who they are.
Amerisleep makes memory foam mattresses and sleep accessories, including pillows and bedding, sold under its own brand. Its mattress line, built around models such as the AS3, uses a proprietary Bio-Pur foam positioned as a plant-based alternative to standard memory foam, aimed at pressure relief and breathability while limiting the heat retention associated with conventional foam. The Flex Pillow extends this approach into pillows designed for cooling and support.
The company centers its identity on all-foam construction offered across multiple firmness options, letting sleepers choose a feel rather than offering a single universal design. Its catalog is framed around cooling, eco-friendly materials, and versatility across sleep positions, targeting buyers who want a foam mattress without the springs or hybrid layers found elsewhere in the category.
The verdict
Amerisleep earns consistent favorable press coverage anchored by strong product reviews and high marketing honesty scores, though it faces routine competitive comparisons that prevent it from standing apart in a crowded mattress market.

AI summary of 4 reviews · as of Aug 2026
Amerisleep is a well-regarded American-made foam mattress brand known for a wide range of firmness options and long warranty coverage, though it is built on the same polyurethane foam materials that critics say soften over time.
What they praise
- Made in the USA, cited across reviews as a point of trust
- Backed by a notably long warranty compared to most competitors
- Offers a broad range of firmness levels (from firm to soft) across its model lineup
- Zoned support layers designed to accommodate different sleeping positions
- Generous trial periods and free returns policy
What they knock
- Built primarily from polyurethane and memory foam, which critics say softens and loses support over years of use
- Warranty language excludes normal softening, so sagging is often not covered
- All-foam models may lack long-term support for heavier body types
- Stomach sleepers and heavier individuals may find the mid-firmness models insufficiently supportive
